transmission cooler lines runs from transmission to the radiator
If your vehicle has an engine oil cooler ther will be two hydraulic lines going to each side of your radiator. If there are only lines going to one side of your radiator, then it doesn't have an engine oil cooler.
Those lines are what oil flows through so it can get to the oil cooler and cool the engine oil down, It helps the life of the engine.
if it has lines going from your oil filter adapter to a cooler in front of your radiator
Yes... If you look at the drivers side of the engine down by the oil filter you will see to lines that run up to the radiator. those are the oil cooler lines.
radiators are used as transmission coolers (typically) and only on automatic transmissions. you will have two metal oil cooler lines that go from the trans to one of the side tanks of the radiator. if you indeed have an engine oil cooler (on newer cars and trucks) you will have an add'tl two lines that go from the engine block (usually at a oil filter adapter housing) to the other radiator tank. if you have a standard trans and still have cooler lines going to the radiator its for engine oil. some but not many vehicles use the engine oil cooler as a total separate cooler usually mounted in various locations around the radiator and it will be smaller.
It could have, some do and some don't. slide in under the truck and look up at the oil filter were it screws onto the engine and if you see 2 medal lines coming from it and running up the side of the engine towards the radiator then it does have an oil cooler on it. If you see NO lines then it don't.
Remove the old oil filter. Drain the oil and remove air cleaner housing. Place the car on Êa jack. Loosen the engine mounts. Raise the engine and loose the bolts on the motor mounts. Remove the engine shock and the two brackets securingÊthe oil lines. Remove the oil cooler lines.
An oil cooler extends the life of an engine by specifically keeping the oil 'cooler' that what the regular cooling system can do (which is designed to cool the entire engine). If your car has some SEEPAGE around the cooler and/or lines that is not the end of the world; but if it LEAKS repair it. Since it is external to the engine I would not expect it to be a major repair.
It there on the passenger side of the radiator then there TRANSMISSION coolant lines and they hook to the transmission. If there on the other side then there OIL cooler lines for the engine.
Leaning over the top of the radiator it should have 2 medal transmission cooler lines on the left side of it. If it has a engine oil cooler then it will have 2 big lines on the right side of the radiator too. That makes 4 lines.
